V CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS i .sAsII GUIDE v IApplication. filed. November 15, 1928. Serial No. 319,509 r Thisinvention has to do with sash guides of the detachable side Wall typedisclosed in Patents Nos. 1,659,657 and 1,659,658, and is particularlyconcerned with the'manner in which the detachable sidewall of the guideis held in position. 1

The purpose of theinvention is to provide, in a guide of thetype'described, improve ments for holding the detachable sidewall inposition. p I v i In order that the invention may be readily understood,one form of the same is presented herein, but it will of course beappreciated that the invention is susceptible of embodiment in otherstructurally modified forms coming equally within the 'scopeoftheclaims.

In the; accompanying drawing:

Fig. 1 is a front view of thelower end of a sash guide equipped with thelatchof the invention;

Fig. 2 is an inner side view; I

Fig. 3 is a rear view; I

Fig. 1 is a vertical section, taken on the line 44 of Fig. 1; and

Fig. 5 is a horizontal section, taken on the line 5-5 of Fig. 2. y g

The sash guide shown in the drawing is characterized by a fixed stripand a detachable strip 11. The striplO is adapted to be fastened to thejamb of awindow frame by screws or other suitable means and is providedat one side with a groove 12 and at the other side with a fixed sidewall-13. If it is desired to have a 'guide from which a'sash may beremoved from either side, the fixed side wall 13 is dispensed with, andanother groove, similar to the groove 12, is provided at that side ofthe strip in place of the fixed side wall. r

The strip 10 is made of sheet metal, and

is bent in such a way as to form the groove 12, the fixed side walls 13and an intervening Web 14. The strip 10 obviously maybe bent in a greatmany other different ways to provide the portions described.

The strip 11 constitutes a removable side wall opposite the fixed sidewall 13 of the strip 10, and is seated within the groove 12 in the strip10. The portion of the-strip 11 within the groove is preferably providedwith a springstrip 15, which is soldered or secured in any suitable,fashion to the inner edge of the strip and extends at an angle from thesame. I

When the guide is not occupied by the stile of a sash, the strip 11 willassume the canted position shown in Fig. 5 under theaction of the spring15, but, when the stile of a sash is in place in the guide, the strip11, upon being inserted in the groove 12 in the strip 10, will be heldby the stile of the sashin a position generally parallel to the fixedside Wall 13 of the strip 10, in which-position the strap 11 will bepressed resiliently againstthe stileof the sash by the spring strip 15.H The strip 11 is held in position in the groove 12 by means of bayonetslots 16 which are formed at'intervals in the rear end of the strip 11andinterlock with rivets 17 which are positioned at correspondingintervals across the groove 12. After the strip 11 has been shiftedrearwardly in the groove and then downwardly into interlocked engagementwith the rivets 17 it is held against upward movementrby means of alatch 18. The e present invention resides in the construction,arrangement and operation of the latch.

The latch 18 consists of a substantially flat and generally rectangularsheet metal slide plate 19 which is shiftable' laterally of the guide ina guideway formed by two rearwardly pressed loops 20 in the web 14 ofthe strip 10. The end of the slide 19 adjacent the groove 12 is reducedand formed into a nose 21, which nose projects through an aperture 22 inthe inner side of the groove 12 into an aperture 23 in the strip 11whenthe slide is shifted in that direction. The movement of the, slidein that direction is limited by engagement of shoulders 24 on the slidewith the inner wall of the groove 12 at the sides of the aperture 22,and is limited in the opposite direction by engagement of the other endof the slide with the rearwardly extending port-ion 25 of the fixed sidewall 13.

In order to maintain the slide in any po-' sition into which it isshifted, the slide is made of spring metal, and is slightly bowed,

as shown in Fig. 5, whereby to cause the end of the slide opposite thenose 21 to press resilientlyagainst the rear face of the Web 14, which"Web may be advantageously corru- V gated at that point to increase theresistance I of the slide to movement. The slide 19 may 7 be easilyshifted into either its latched or its unlatehed positionby theemployment 01 an ordinary screw" driver. -A'na'rroW notch 26 is formedin one s'ideof the slide, and a .relatively wide V-shaped notch 27 isformed 7 in the Web-'14 in diverging opposi'tion' 110- the notch 26. Inorder to sh'i'ftth'e slide, the end of the blade of a screwdriver, shownin dotted lines at 28 in Fig. 4, is inserted. into the composite socket.formed by the notches a V Q6 and 27, and is turned in one direction orvtheother, employing the narrow end of the V-shaped notch'27as a fulcrumin effecting the turning movement. 1 j I claim: v v r V 20, 1;.
